OUSHIONING DEVICE FOR VEHICLES.

To all whom it may concern:

Be it known that we. Atnxixm-za CARPEX- for nee in connection withvehicles. and it is more particularly an improvement upon the tructureshown in an application for ['nited States Patent filed by us on October30th.

190?. said application bearing Serial No. 399.897. and u applicationlied by us on May 7th. 1908, Serial No. 431332.

The object of the invention is to pron'de a pneumatic spring havingmeans of novel construction for supporting it below the axle of thevehicle to which the spring is ab inched.

A further object of the invention is to proride :1 spring-engagingmember movably mounted relative to the support of the spring cushion andhaving whereby displacement of said nielilber relative to the pneumaticspring is prevented.

A still further object is to provide a pncumatic spring of thischaracter which can be readily placed in position upon the axle of avehicle.

With the above and other objects in view the invention consists ofcertain novel details of construction and combinations of partshereinafter more fully described and poixliltetll1 out in the claimsam te occom anying win the referred form oft e invention has fien shtiirn.

In said drawings :Figure 1 is a front eleatten of a sprin embodying thepm=ent IIIIPIOVBIHEDtE, sai sp n being shown in position upon a vehiclea e. Fig. 2 is a section on line A-B Fig. 1. Fig. 3 is a section on lineC-D Fig. 1.

Refe to the figures by characters of reference, A designates the axle ofa vehicle, the some belng designed to extend through an eloliatedcylindrical sleeve 1 having oplposit flanges 2 t ereon. extend inopposite direct-ions from a ceutralrectangula r collar 3 the frontandrent, or beet-131% lle faces of which are providedwith para guideflanges .4. Although the sleeve. 1 is preterfibly formed in one piece,the same Specification of Letters Patent.

Application tiled October 2. 1908. Serial No. 456.841.

1 the structure shown in un y disposed longitudinal Patented Feb. 28,1909.

9 mar. if desired. be split into two sections at each end. each of thesections being provided with flanges 2 designed to be secured together bmenus of bolts 01 other devices such as indicated at 5 in the drawings.

Uppositelv disposed pairs of downwardly f converging llilllfItElS 6 areformed with or secured to the lower flanges 2 of the device I close tothe ends of the sleeve 1. The lower as indicated at T and are secured inunv preferred manner to the lower or convex fare of u rom-uvo-couvexsupporting disk 5. It is of cums-e to be understood that if preferredthese haugem may be cast or otherwise i formed integral with thesupporting disk 8. An inflatable sphere J is mounted on the disk 8 andis rovided with a valve 10 whereby air may e retained within the sphereunder pressure. This sphere supports a concave-convex cap 11 on whichare mounted spaced parnllel standards 12. Said standards are arranged ato )posite sides of the collar 3 and :i re designe to slide between theflanges 4.

A bowed top plate 13 is secured upon the standards and interposedbetween the end portions of the top plate and the andards 2 and the cupll are ieinforced webs 14. The plate 13 conhtitutes a bearing for avehicle spring B which may be secured there to in any preferred manner.

The device herein described is designed to be placed upon-the market asan article of manufacture. When it is desired to place the device uponan axle said axle is inserted throu the sleeve 1 and if the sleeve ismade up 0 -sections the name can be tightened t i plon the axle by meansof bolts or screws 5.

e hangers 6 will therefore extend downwardly below the axle while thestandards 12 will be positioned in front of and back of the axlerespectively. The vehicle spr' can be attached to the top stri or late 3and the here 9 after he p ce loosely between t e sn porting 8 and thecap 11, can be infliited so as to hold the ca ends of (i195? lmngew arecurved upwardly
